Operation
Condensation pump
The water is drawn off by the condensate pump and discharged
along a hose (supplied loose) connected on the pressure side .
Depending on conditions on site, the water can be discharged into
drainage lines, possibly with a trap connection .
A float switch monitors the water level and switches the pump off
if it is exceeded . The condensate is drained off . In the event of a
fault with the condensate drain, the water level will continue to rise
until the float switch triggers an alarm contact. The contact can be
analysed by external signalling devices .
We would recommend automatically terminating cooling operation,
possibly with a shut-off valve, if the alarm contact is triggered to
prevent the condensate tray from overflowing.
Condensate drain (accessory)
• Drainage of condensate from the condensate pump has to be
provided along a natural gradient with an adequate cross-section
(minimum 1/2“). Increase the cross-section of the line with longer
condensate lines.
• Check whether the condensate line needs to be insulated to prevent
the build-up of condensate along the line.
• Do not use a rigid transition to the on-site condensate drain, as this
lengthens the pump‘s pressure hose. We would recommend free
overflow into a trap.
• Refer to chapter 6.11 on page 53 for further information on
condensate drainage.
Installation of the condensate pump (accessory)
Cabling
The condensate pump needs a separate power supply (230
V/50 Hz). We would generally advise against connecting it via the
room thermostat, as residual condensate could be produced after it
has been switched off . Additional wires are needed to analyse the
alarm contact .
Use the following types of cable:
Mains supply: NYM-J , 1.5 mm
2
Alarm contact The cable for the alarm contact depends on the kind
of alarm analysis used (e .g . shielded cable) .

Carry out an initial service on the condensate
pump and float switch directly after
commissioning.
